Adsorbent properties and aqueous characteristics are very important parameters in the removal efficiency (RE) of environmental pollutants. The main goal of this study was to investigate the effects of pH, particle size and porosity of raw rice husk and its silica on removing lead and hexavalent chromium (Cr+6) from aqueous solution. The raw rice husk was collected from north of Iran and the ric...

40 41 Background: To investigate more practical handling of Borg’s ratings of perceived exertion 42 (RPE) and category-ratio scale of RPE (CR-10), we evaluated interrelationships between RPE, 43 CR-10, and blood lactate concentrations ((La)b) during incremental treadmill running tests for 44 young females with different aerobic fitness levels. 45 Methods: Oxygen consumption, heart rate, (La)b, ...

background: considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. the purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane bioreac...

Caloric restriction (CR) extends lifespan through a reduction in oxidative stress, delays the onset of morbidity and prolongs lifespan. We previously reported that long-term CR hastened clinical onset, disease progression and shortened lifespan, while transiently improving motor performance in G93A mice, a model of amyotrophic lateral sclerosis (ALS) that shows increased free radical production...

Conventional resuscitation (CR) from hemorrhagic shock (HS) results in gut and liver hypoperfusion, organ and cellular edema, and vital organ injury. Adjunct direct peritoneal resuscitation (DPR) with dialysate prevents gut vasoconstriction, hypoperfusion, and injury. We hypothesized that DPR might also improve hepatocellular edema, inflammation, and injury. Anesthetized male SD rats were assig...

To develop Bi2S3-based heterojunction for efficient solar light induced photoreduction of Cr(VI), flower-like Bi2S3–In2S3 composites consisted nanorods were prepared via a microwave-assisted hydrothermal route. In contrast with pure Bi2S3, exhibited the enhanced activity while decreased adsorption capacity Cr(VI) removal. The best removal efficiency 70 mg L?1 solution (99.86%) was achieved by o...

N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide was used as a selective sensing material in the PVC membrane to construction of a new chromium ion selective electrode. This liquid membrane electrode worked well with a Nernstian response of 19.7 ±0.4 mV decade-1 of Cr(III) in a wide dynamic concentration range of 8.0× 10-6-1.0×10-1 M. The electrode had relatively short response time ...

Arthropod venoms are complex mixtures of enzymes, proteins, histamines, and other bioamines that can either damage tissue directly or elicit an allergic response. The venoms of each family are unique, and cross-reactivity is rare with the exception of wasps, hornets, and yellow jackets (vespids). Local tissue reactions from dermal exposure to arthropod antigens result in the common pruritic, ur...

Either calorie restriction [CR; consuming 60-65% of ad libitum (AL) intake] or acute exercise can independently improve insulin sensitivity in old age, but their combined effects on muscle insulin signaling and glucose uptake have previously been unknown. Accordingly, we assessed the independent and combined effects of CR (beginning at 14 wk old) and acute exercise (3-4 h postexercise) on insul...
